螺旋扰流板对单桩基础局部冲刷的水动力弱化及防护效果分析
The effects of spiral spoiler around monopile for hydrodynamic weakening and local scour protection
摘要
Abstract
From the perspective of disturbing the horseshoe vortex at upstream edge and wake vortex at downstream edge,the new spiral spoiler installed on the surface of monopile to prevent scour in marine environment.The scour evolution and flow field around monopile were investigated by numerical model for the case of installing spiral spoiler and without spiral spoiler respectively.The results indicate that the seabed suffers the gentler scour around monopile for the case of installing spiral spoiler,and the scour depth decreases about 11.24%to17.60%,instructing the spiral spoiler can mitigate scour evidently.The spiral spoilers decrease the scale of onset of scour by mitigating inflow at upstream edge,and weak the energy of wake vortex by decreasing flow acceleration at downstream edge.In this way,the spiral spoilers protect the seabed from scour efficiently.关键词
